不同土地利用类型的地表亮温变化特征OA
Surface Brightness Temperature Variation of Different Land Use Types
[目的]研究不同土地利用类型的地表亮温变化规律.[方法]基于2008年的MODIS数据,以长三角为研究区,结合IGBP土地分类体系,计算地表亮温,总结规律,并对原因进行探讨.[结果]不同土地利用类型有其独特的亮温变化.白天亮温大小为草地、建筑用地＞农田、林地和荒地＞湿地和水体；夜间亮温大小为水体、湿地、荒地＞建筑用地、草地＞林地、农田.亮温全年呈现冬低夏高、春增秋减的趋势.夜间亮温更能反映地表热辐射特点.太阳辐射、混合像元、比热容、含水量等是导致…查看全部>>
[Objective] The aim of this study is to investigate the surface brightness temperature variation of different land use types. [ Method] Based on MODIS data in 2008 and 1GBP land classification system, the surface brightness temperature in the Yangtze River Delta area was calculated, and its rules and reasons were also discussed in this study. [ Result] the Different land use types had its own special brightness temperature variation. During the day, the brig…查看全部>>
